BALING-PRESS.

SPECIFICATION forming part of Letters Patent No. 543,632, dated July 30,1895.

Application filed September 18, 1894- Slerial No. 523,415. (No model.)

To all whom it may concern.-

Be it known that we, AMOS ROOP, FRANCIS L. BRANDON, and JOHN S. HART,citizens of the United States, residing at Hicksville, in the county ofDefiance and State of Ohio, have invented a new and useful Baling-Press,of whichv the following is a specification.

Our invention relates to baling-presses particularly adapted for balinghay, and the objects in view are to provide a simple, direct, andefficient power for operating balingpresses; to provide means for balingin opposite directions alternately or with both motions of the plungers,whereby uniformity of the resistance to the plunger is obtained; toprovide an automatic feed mechanism for the baling-ohamber, and,furthermore, to provide an improved construction of balingchambers tofacilitate the removal of the bales after completion.

Further objects and advantages of our invention will appear in thefollowing description, and the novel features thereof will beparticularly pointed out in the claims.

In the drawings, Figure 1 is a perspective view of a baling-pressembodying our invention. Fig. 2 is a detail view, partly in section,taken longitudinally, of the mechanism for transmitting motion from thedriving-shaft to th'e'plungers. Fig. 3 is a detail longitudi nal sectionof the automatic feed mechanism. Fig. 4 is a similar view of thebaling-chamber proper. Fig. 5 is a transverse vertical section of thesame, showing the means for securing the parts of the chamber in theirclosed or operative positions.

Similar numerals of reference indicate corresponding parts in all thefigures of the drawings.

1 designates the parallel-sided frame of the machine, at the extremitiesof which are arranged the baling-chambers 2', and 3 represents the poweror operating mechanism, which is arranged at a point between saidbaling-chambers and communicates motion to the rods 4 of the plungers 5.

6 represents the driving-shaft, whichis mounted in bearings 7 inopposite sides of the frame 1, any suitable means being provided for thecommunication of rotary movement to the said shaft. Fixed to thedrivingauxiliary eccentrics.

bifurcated inner ends of the plunger-rods.-

The spindles lOare extended laterallyto form guide-pins 12, which fit inhorizontal guideslots13 in the sides orwalls of the frame 1.

Any suitable means may be provided for the communication of rotarymovement from the master eccentric to the auxiliary eccentrics duringthe contact of the latter with the former, but in the constructionillustrated in the drawings we employ peripheral spurs 14 on the mastereccentric for engaging peripheral sockets or notches 15 in the auxiliaryeccentries. In this connection we also employ retraction or reboundingsprings 16, attached at one end to the framework below the plunger-rodand at the other end to the plunger, whereby an even pressure of theauxiliary eccentrics upon opposite sides of the master eccentric ismaintained throughout the operation of the machine.

The master and auxiliary eccentrics are of equal diameters, whereby eachof the auxiliary eccentrics makes a complete revolution during onerevolution of the master eccentric, and the auxiliary eccentrics aredisposed respectively in opposite positions, or with their enlargedportions or major diameters extending in opposite directions. Also, themaster eccentric is so arranged with relation to the auxiliary eccentricthat when its major diameter is in a horizontal position it is inalignment with the major diameter of one of the Thus, as the enlargedportion of the master eccentric is presented successively to the twoauxiliary eccentrics, the major diameters of said auxiliary eccentricsare presented successively to the major diameter of the mastereccentric. In this way the plungers which carry the auxiliary eccentricare alternately advanced or moved outward from the power or operatingmechanism, the advanced movement of one of the plungers beingaccompanied by the return movement of the other plunger.

Extending longitudinally over the balingchamber 2 at each end of theframework is a beam 17, and to this beam are hinged the walls 19, saidhorizontal portions combining to form the top or cover of the press-box.The side walls proper, or the vertical portions thereof, are hinged attheir lower edges to the base of the framework, and the horizontal partsof the top or cover are provided with locking devices for engagingupstanding ears or studs 20 on the side walls proper. These lockingdevices may consist, as shown in the drawings, of aspindle 21, mountedin hearings in suitable brackets 22, and provided with a handle 23, saidspindle carrying tongues 24, provided with terminal shoulders 25, toengage said ears or studs 20. The operatinghandle 23 is provided with acam-head 26 to bear upon the upper surface of said top or cover, wherebythe locking-tongues are held out of engagement with the ears or studs onthe side walls of the press-box.

Arranged in each of the press-boxes is a spring-actuated or reboundingfollower 27, fitting snugly in the box and provided with parallelguiding-rods 28, which fit in guide-openings 29 in a terminal standardor block 30.

Coiled upon these parallel rods and bearing at opposite extremitiesagainst the follower and the bracket or block are the springs 31.

In addition to the above-described mechanism, we also employ anautomatic feeding device, one for each press-box, the same beingprovided with a hopper 32 and an oscillatory packer 33, which isarranged in the lower portion of the hopper, and is adapted to depressthe material to be baled and force it into the are alternately engagedby the projections to throw the packer in opposite directions, and thusfeed the hay or other material from the hopper into the press. Saidsliding-fulcrum levers are pivotally connected at their upperextremities to the packer, and the sliding fulcrums are formed byextending the levers through swiveled guide blocks or bearings 39.

From the above description it will be seen that as theoppositely-disposed plungers are alternately advanced and retracted theycommunicate an oscillatory movement to the packers located in thehoppers or adjacent to the feed-openings of the press-boxes, whereby itis only necessary for the attendant or operator to place the hay orother material in the hopper. Furthermore,it is obvious that, inasmuchas one of the plungers is advanced while the other is retracted, theresistance to the advantages of the invention.

Having thus described our invention, we claim- 1. In a baling press, thecombination with a reciprocatory plunger, of a master eccentric andmeans for communicating motion there to, an auxiliary eccentric mountedupon the rod of said plunger and operatively connected with said mastereccentric, whereby motion is communicated from the latter to the former,and means forguiding the auxiliary eccentric to cause its center ofrotation to reciprocate in a straight line, substantially as described.

2. In a baling press, the combination with a plunger, of a mastereccentric and means for operating the same, said master eccentric beingprovided with peripheral spurs which are tapered toward theirextremities, an auxiliary eccentric mounted upon the rod of said plungerwith its major diameter in opposition to that of the master eccentricand having peripheral notches or sockets to receive the spurs of themaster eccentric whereby relative lateral displacement of the eccentricsis prevented, and means for guiding the auxiliary eccentric to cause itscenter of rotation to reciprocate in a straight line, substantially asdescribed.

3. In a baling press, the combination with oppositely disposed, alignedbaling chambers, and plungers mounted for reciprocation therein, of amaster eccentric arranged between the baling chambers, auxiliaryeccentrics mounted for rotation upon the rods of said plungers, thefaces of the main and auxiliary eccentrics being constructed to.intermesh, whereby rotary motion may be communicated from the master tothe auxiliary eccentrics, means for guiding the auxiliary eccentrics tocause their centers of rotation to reciprocate in a common horizontalplane and resilient devices attached to the plungers for normallyholding the auxiliary eccentrics in operative relation with the mastereccentric, substantially as described.

4. In a baling press, the combination with a plunger andoperatingmechanism, of abaling chamber having hinged side walls, adivided top or cover having its parts or members hinged at theiradjacent inner edges and means for locking said hinged parts in theirclosed or operative positions, such means consistin g of shoulderedtongues, ears or studs on the side walls for engagement by the tongues,a spindle mounted in brackets upon the top or cover and carrying saidtongues, and an operating handle attached to the spindle and providedwith a cam head for maintaining the tongues out of engagement with theears or studs, substantially as described.

5. In a baling press, the combination with a plunger and operatingmechanism, of a baling chamber provided with movable walls forfacilitating the removal of a bale, and a resilientspring-pressedfollower arranged in the chamber and having parallel rods fitting inguide openings in a fixed standard or block, and actuating springscoiled upon said rods and bearing at opposite extremities against thefollower and said standard or block, substantially as described.

6. In a baling press, the combination with a baling chamber, a plungerand operating mechanism, of feed mechanism having an oscillatory packerarranged adjacent to the feed opening of the baling chamber, sliding-fulcrum levers connected to the packer, and projections on the plunger forengaging and communicating motion to the said levers, substantially asdescribed.
